Context Awareness Acquisition for Safety Sensor Data Processing on Industrial Sensor Network

Abstract

As USN environment begins to be applied into many fields, the installation of USN node onto portable devices has become a possibility. And as the use of portable node has become a possibility, the applicative directions of USN environment are being studied, particularly in the field of industrial control system. But, with the application of USN environment into industrial environment, there occurred many problems such as efficient processing of sensor stream data, heterogeneous sensor node management, efficient processing of image data, lack of context awareness technology using sensor data, etc. So, this study aims to propose integrated sensor data control system for processing sensor stream data and provide a system for managing meta-data in USN environment. It also proposes context awareness system that provides context awareness using sensor data and simplified context information model. For the implementation of this work and performance evaluation, this study builds context awareness control system that provides user interface with integrated data and image so that users are able to perform industrial control efficiently. And it also proposes a scenario with the system in this study applied.
